Objective

The aim of the present study was to proove the value of the HMC-anomaloscope with the standard 2Â°-ocular to detect acquired colour vision disturbances in patients with arterial hypertension.

Methods

Sixty-one patients (f:m=33:28) with arterial hypertension and without damages in end-organs were included in the study being divided into 3 groups according to their blood pressure levels during their long-term treatment: Group 1: systolic/diastolic blood pressure: 120-139/80-89mm Hg (n=17, f:m=12:5, average age = 55Â±14 years), group 2: systolic/diastolic blood pressure: 140-159/90-99mm Hg (n=25, f:m= 10:15, average age = 56Â±12 years), group 3: systolic/diastolic blood pressure: 160-179/100-109mm Hg (n=19, f:m= 11:8, average age = 55Â±11 years). They were compared to 20 healthy controls (f:m=12:8, average age = 54Â±12 years). Exlusion criteria were eye and general diseases. Beside the ophthalmological status (visual acuity, refraction, intraocular pressure, cup/disk ratio, fundus) the HMC-anomalscope was applied and the Moreland-and Raleigh match calculated. Statistical analysis was performed with the Mann-Whitney-U-Test and Wilcoxon-Test.

Results

The ophthalmological examinations showed a fundus hypertonicus stages I-II in 15 patients. Statistic analysis showed no significant difference of Moreland- and Raleigh match between the patients with arterial hypertension and the control group (Mann-Whitney-U-test: p>0.05). There was also no significant difference between the three hypertonic groups (Mann-Whitney-U-test: p>0.05).

Conclusions

The examination of acquired colour vision disturbances in patients with arterial hypertension using the HCM-anomaloscope seems to be less sensitive to the cap-sorting test Roth 28-hue (E) desaturated. Probably this results are caused by the small visual field of 2Â°. Further studies are necessary to clarify the value of increased visual field.
